4.1 working mode
When the product work in manual mode, the Settings below
When the switch switch from automatic mode to manual mode, switch power supply voltage automatic detection, such as entering a state allows switching voltage normal, allow manual switching.
When the product work in automatic mode, the Settings below
Overpressure value 265 v + 5 v, under voltage value to 175 v + 5 v.
Products through about 30 seconds after normal voltage, automatic reset switch when detecting voltage is normal. Unable to switch and a single flash when overvoltage, undervoltage when not closing and double flash.
Over voltage protection: over voltage (265 v + 5 v) and for 1 seconds after the trip, if after the trip voltage return to normal voltage (235 v + 5 v) and closing for 30 seconds.
Under-voltage protection, under voltage (175 v + 5 v) and for 1 seconds after the trip, if after the trip voltage return to normal voltage (190 v + 5 v) and closing for 30 seconds.
Loss of pressure protection: normal voltage drops to below 110 v more than 0.5 seconds, tripping directly, cannot be a manual switch.
4.2 the other
This product has good current limiting characteristics, arc very short time, high breaking capacity and protective properties, long service life, stable performance and reliable precision, at the same time has obvious sign the contact position of the state and control the signal light. Connection terminal adopts frame structure, solid and reliable.
